Purpose Recently, there has been an increase in attempts to analyze social phenomena, consumption trends, and consumption behavior through a vast amount of customer data such as web search traffic information and social buzz information in various fields such as flu prediction and real estate price prediction. Internet portal service providers such as google and naver are disclosing web search traffic information of online users as services such as google trends and naver trends. Academic and industry are paying attention to research on information search behavior and utilization of online users based on the web search traffic information. Although there are many studies predicting social phenomena, consumption trends, political polls, etc. based on web search traffic information, it is hard to find the research to explain and predict tourism demand and establish tourism policy using it. In this study, we try to use web search traffic information to explain the tourism demand for major cities in Gangwon-do, the representative tourist area in Korea, and to develop a nowcasting model for the demand. Design/methodology/approach In the first step, the literature review on travel demand and web search traffic was conducted in parallel in two directions. In the second stage, we conducted a qualitative research to confirm the information retrieval behavior of the traveler. In the next step, we extracted the representative tourist cities of Gangwon-do and confirmed which keywords were used for the search. In the fourth step, we collected tourist demand data to be used as a dependent variable and collected web search traffic information of each keyword to be used as an independent variable. In the fifth step, we set up a time series benchmark model, and added the web search traffic information to this model to confirm whether the prediction model improved. In the last stage, we analyze the prediction models that are finally selected as optimal and confirm whether the influence of the keywords on the prediction of travel demand. Findings This study has developed a tourism demand forecasting model of Gangwon-do, a representative tourist destination in Korea, by expanding and applying web search traffic information to tourism demand forecasting. We compared the existing time series model with the benchmarking model and confirmed the superiority of the proposed model. In addition, this study also confirms that web search traffic information has a positive correlation with travel demand and precedes it by one or two months, thereby asserting its suitability as a prediction model. Furthermore, by deriving search keywords that have a significant effect on tourism demand forecast for each city, representative characteristics of each region can be selected.

나는 태국 방콕에 소재한 Mahidol 대학교 국제학부에서 애니메이션 교육자로서 지난 8년동안 태국의 신 세대 애니메이터의 작은 집단을 교육하는 특권을 지닌 위치에 있었다. 태국은 태국 고유의 애니메이션 실험적용이 그 동안 거의 없었으며, 그런 다양성에 접근도 인터넷 이전 시대에는 제한이 있었다. 이런 이유로 나의 연구 배경이 되는 특히 영국과 유럽의 풍요로운 애니메이션 역사를 강의실로 가져와 소개하려는 시도를 해왔다. 특히, 내가 가르치는 데 있어서 둔 목적은 초기의 (또한 현재의) 실험적/독립 애니메이터들이 탐구했던 매체, 양식과 텍스트 네러티브(서사) 선택에 관한 다양한 가능성을 소개하는 것이었다. 최초의 장편 상업 영화 "Khun Kluay"가 2006년에 출시된 이래로, 태국의 애니메이션 산업은 그간 외국에서 훈련 받고 일하고 돌아온 숙련된 인력을 형성하면서 상업적인 부면에서 여러 기복을 겪어왔다. 현재는 독립 애니메이션이 출현하기 시작하는 확실한 증거가 보인다. 태국 애니메이션에 관한 나의 연구의 연장으로, 본 논문은 선정된 독립작품에 대해서 그 주제를 비롯해 사용된 양식과 테크놀로지를 탐구하면서 세밀하게 분석하고자 한다. 그러나 동시에 해석에 대한 오류의 가능성도 인정할 수 밖에 없을 것이다. 나의 문화적 언어와 해석은 아웃사이더의 관점이기 때문에 본래 크리에이터의 경험을 초월할 수도 있고 대안적인 해석을 추가할 수도 있을 것이다. 본 논문은 작품의 내용과 아이디어와 문화적인 관점을 맥락화하고, 더 많은 태국의 작품들이 애니메이션 연구 학계에 시선을 모을 수 있는 것을 목적으로 한다.

Lots of virtual communities and online businesses presently derive their primary sources of revenues through advertising, but nevertheless are plagued with marginal profitability though they might possess a significant user base. In the light of the need for an efficacious business model, there have been recent insights of an online community in particular reaping profits through an innovative and lucrative revenue generation method that earns by selling digital items. There have been some obvious evidences (e.g., Cyworld, SecondLife, Habo Hotel, etc.) that online communities can be profitable through their unique business model of selling digital items. However, there is lack of understanding about the motivation of purchasing digital items. This study tries to identify the main motivators of digital item purchases based on social/individual identity theory and self-presentation theory. "Digital items", otherwise known as "virtual assets", may include online avatars, accessories for the avatars, decorative ornaments like furniture, digital wallpapers, skins, background music and virtual weapons used for Internet games. These digital items are employed by users for representation and articulation in the online space, especially to create and enhance their online profiles in web pages and games. Prices for digital items typically range from a few cents to a few dollars each. Based on the theoretical framework like social identity theory and self-presentation theory, we developed the research model and proposed seven hypotheses. An analysis of 225 members of Cyworld found that digital item purchase intention in virtual world is affected by both members' need for self-presentation and need for affiliation. We also found that the need for self-presentation is significantly increased by innovativeness of members, community group norm, and community involvement. We concluded that the need for self-presentation could be a key variable for profitable business model in online community service industry. However, neither individual self-efficacy nor the need for affiliation significantly influenced the need for self-presentation which triggers purchase intention of digital items. In term of the theoretical and practical contribution, this study can be a pioneering empirical research that investigates the purchase intention of digital items based on social identity theory and self-presentation theory in the online context. Also, the findings of our study are valuable and practical for practitioners in the market who wish to adopt or improve the business model of selling digital items in an online community. From the findings, it can be seen that innovativeness of users, community group norm, and community involvement are three significant factors that influence need for self-presentation of users which ultimately leads to their intentions to buy digital items. These findings put forth that virtual community providers and online businesses selling digital items should prioritize their efforts and focus on these three factors if they want to increase the sales of these digital items and generate greater revenues. This study provides important implications for academic researchers and practitioners to understand why the community members pay money for their digital items in virtual world and how the practitioners can increase the sales of digital items in an online community. A couple of limitations of the study and future research directions are also discussed.

그 동안 문화정보에 관한 연구는 개별 문화정보가 중심을 이루어 왔으며, 그 연구내용은 종이지도를 이용한 권역 설정에 그 초점이 맞추어 졌다고 볼 수 있다. 그 결과 극히 제한적인 계량적 공간분석과 지도상에 보이는 직감적인 분석은 복잡하고 방대한 문화자료를 체계적이고 과학적으로 정리하고 활용하는데 한계가 있었다. 이러한 문제점을 해결하는 방안으로 지역문화정보에 대한 효율적 관리체계의 구축과 문화정보의 시공간적 역동성을 총체적으로 분석할 수 있는 GIS의 도입은 필수 불가결하다. 특히 오늘날 고도 정보산업에 의해 문화 전달속도가 빨라지고 가치가 다변화된 사회구조에서는 편방향의 정보제공이 아닌 양방향 정보제공이 중시되고 있다. WebGIS에 기반을 둔 지역문화정보시스템은 사용자가 인터넷을 이용하여 다양한 문화정보에 대한 시 공간적인 분석과 통계적 분석을 가능하게 됨으로서 WebGIS를 이용한 호남문화정보시스템은 지역정보에 대한 포괄적인 접근이 용이할 뿐만 아니라 문화 개별요소간의 통계 분석을 통한 새로운 정보의 창출과 지역 간 비교 연구에 기여할 수 있을 것으로 생각한다.

The objective of this research is to unveil the dynamic changes of the trends in wedding dresses during the 20th Century. The studies were carried out in two forms; firstly by observing the actual wedding dresses worn by people at that time, and secondly by conducting formative comparisons between those dresses with the ones appeared in movies corresponding to that period. Movies provide an invaluable insight into the era's wedding dresses fashion trends since they function as intimate bridges in connection with the time's audience, and the visible imageries accurately reflect the characteristics embedded within that time frame. As there are no precedent studies regarding this topic, this thesis can serve as vital research data for the wedding dress industry. Research data regarding the actual wedding dresses were collected from books and museum web sites. The object of movies were films produced before World War II that contained both the background settings of the 20th Century and wedding dresses, of which photographic imageries were captured. Research analysis was then conducted by merging these data with findings from relevant books and internet materials. The results of the thesis are as the following: The 1900s was an extension of the 19th Century's popular fashion trend which can be characterized as the S curve silhouettes of the Edwardian period when long trains and long veils symbolized wealth and social power. In the 1910s, high waist silhouettes with soft wrinkles were prevalent as attire suitable for active mobility with practical functionality were highly regarded. During the 1920s, the flapper style became the dominant trend. Hem lines of the skirts were curled in the form of the scallop and laces were the most widely used raw materials. By the 1930s, wedding dresses that reinterpreted the glamorous sheath lines, practical two piece styles, and retro-styles became predominant. The 1940s saw the advent of ready-made wedding dresses made of synthesized materials; practical military style suits and casuals sometimes substituted the wedding dresses. And although the wedding dresses in the movies were primarily costumes to express the personalities of the characters, they were also reinterpreted as manifestations of the formative characteristics of each relative period that pursued very distinct and diverse features.

피싱 공격은 시간이 흐르면서 보다 더 지능적으로 실행되며, 기술적으로 고도화되고 있다. 해커는 지능화된 피싱 공격을 주요 기관의 내부 네트워크 침투를 위해 내부 사용자 컴퓨터를 점령하는 수단으로 이용하고 있다. 따라서, 본 연구에서는 고도화된 피싱 공격으로부터 내부 사용자와 중요 정보를 보호하기 위해 피싱공격 확산방지모델(PMPA : Prevention Model the spreading of Phishing Attack)을 기술하고자 한다. 내부 사용자들은 외부 웹메일 서비스와 내부 메일 서비스를 동시에 사용한다. 따라서 양 구간에서 발생하는 위협 요소를 동시에 식별하기 위해서는 각각의 패킷을 감시하고 저장하여 각각의 항목별로 구조화시켜야 한다. 이는 해커가 내부 사용자를 공격할 때 외부 웹메일 서비스와 내부 메일 서비스 중 어느 한 쪽을 이용하거나 또는 양쪽 모두를 이용할 수 있기 때문이다. 본 연구에서 제시된 모델은 기존에 연구된 메일 서버 중심의 보안구조 설계를 내부 사용자가 접속하는 내부 메일 서비스까지 보호할 수 있도록 확장한 것이며, 프록시 서버를 이용하여 직접 피싱 사이트 접속을 차단하는 것보다 메일 확인 시 해당 사이트를 목록화할 수 있기 때문에 별도의 요청/응답을 위한 대기 시간이 없다는 장점이 있다.
